Application May 9, 1955, Serial No. 506,849

1 Ciaim. (Cl. 74-507) The present invention relates to dispenser handles, and more particularly to tape dispensers of the type which dispense a predetermined length of tape, moisten it and cut it off at a predetermined point.

The primary object of the invention is to provide a dispenser handle which will simultaneously drive the dispenser mechanism and limit the quantity of tape dispensed.

Another object of the invention is to provide a device of the class described in which the dispenser drive mechanism is formed as an integral part of the handle and the stop mechanism is also formed integrally therewith.

A further object of the invention is to provide a device of the class described in which a gear rack is formed on the handle for rotating a drive gear on the dispenser.

A still further object of the invention is to provide a device of the class described which is inexpensive to manufacture, non-complex to install on a tape dispenser, and incapable of becoming maladjusted.

Other objects and advantages will become apparent from the following specifications when read in light of the attached drawings, in which:

Figure 1 is a side elevation of the invention shown attached to a tape dispenser, with parts broken away.

Figure 2 is a horizontal cross-section of the device taken along the line 22 of Figure 1, looking in the direction of the arrows.

Figure 3 is a vertical cross-section of the device taken along the line 3-3 of Figure 2, looking in the direction of the arrows.

Figure 4 is a top plan view of the finger contact portion of the handle.

Figure 5 is a fragmentary horizontal cross-section of the stop mechanism, taken along the line 5-5 of Figure 3, looking in the direction of the arrows.

Now referring to the drawings in detail, wherein like reference numerals indicate like parts throughout the several figures, the reference numeral indicates, generally, the end casing of a tape dispenser of the type adapted to dispense, moisten, and sever a length of gnmmed tape, and in which the length of the dispensed tape may be varied.

A shaft 11 extends from the dispenser 10 and carries on its outer end a pinion gear 12. The pinion gear 12 is adapted when rotated to rotate the shaft 11 and thus drive the dispensing mechanism contained within the dispenser 10. Upon the reverse rotation of the pinion 12, a cutter (not shown) is adapted to cut the dispensed tape, thus freeing it for use. A shaft 13 also extends from the dispenser 10 and is adapted to act as a journal, the purpose of which will be later described.

A one piece handle 14 is provided with a head 14a having a tubular boss 15 which is adapted to be positioned on the shaft 13 for rotation thereon. The head has a recess 14b extending from the boss 15 and having an arcuate side 140. An internal rack 16 is likewise .2,8ll8,734 Patented Oct. 8, 1957 formed on the handle 14 and is provided with teeth 17 which are formed on the arcuate side 15a which has its center coaxial with the center of the tubular boss 15. The teeth 17 on the rack 16 are adapted to engage the pinion 12, so that rotation of the handle 14 about the shaft 13 will cause the rack teeth 17 to drive the pinion 12.

The handle 14 is offset outwardly, as shown in Figure 4, to provide clearance for the hand of the operator, and the outer end of the handle has a roughened finger pad 18 formed thereon for engagement by the finger of the operator.

The tubular boss 15 has an arcuate segment removed therefrom along the lower side of the boss 15-, forming an arcuate slot 19. A flat plate 21 is pivotly mounted on the shaft 13 between the boss 15 and the casing 10. This plate is provided with an arcuate slot 22 coaxial with the shaft 13. Gn this plate 21 is fixed a pin 20 which engages in the slot 19 and is adapted to limit the rotation of the handle 14. This provides for regulating the length of the tape dispensed from the dispenser. A headed screw 23 extends through the slot 22 of the plate 21 and engages in the casing 10. This screw serves to hold the plate 21 in any position to which it may be adjusted.

In the use and operation of the invention, the finger pad 18 of the handle 14 is depressed in the direction as indicated by the arrow in Figure 1, thus rotating the pinion 12 and the shaft 11, driving the dispenser mechanism in the dispenser 10. The shoulder 25 formed at one end of the arcuate slot 19 engages the stop pin 20 and stops further movement of the handle 14. Upon release of the handle 14, it is returned to its starting position by spring means inside the dispenser, and simultaneously thedispensed tape is cut, releasing it from the machine. When it is desired to vary the length of the tape that is dispensed from the machine, the stop pin 20 is revolved about the shaft 13 to the desired position by loosening .the screw 23 and moving the stop plate 21 to the desired position, whereupon the screw 23 is retightened, locking the stop plate 21 and stop pin 20 in their new position.

Having thus described a preferred embodiment of the invention, it should be understood that numerous structural adaptations and modifications may be resorted to without departing from the scope of the appended claim.

What is claimed is:

A handle for operating a shaft of a dispenser and including a head recessed on one side, a gear fixed on said shaft, a lever member projecting from said head for rocking the head on said shaft, an internal rack formed in said head and engaging said gear, a boss formed on 'said head, a shaft extending from a dispenser mechanism into said boss and forming the axis on which said head rotates, said boss having an arcuate slot extending therearound and having stop shoulders at its ends, a pin engaging in said slot, a plate mounted coaxially with said boss and carrying said pin, said plate extending from said boss and having an arcuate slot therein coaxial with said boss and an adjusting screw extending through the slot in said plate and constituting locking means for holding the plate in adjusted rotation on the boss.
